Abstract

The invention desires to further enhance the steering action of electro hydraulically actuated steering systems. To this end, a hydraulic steering system is provided for use in transport vehicles, comprising: a co-steered axle comprised of wheels and steering arrangements for steering the wheels; a hydraulic pressure circuit (1000) comprised of a hydraulic fluid pump (1008); first and second pressure control modules (1009, 1010); first and second pressure supply terminals (1004, 1005) arranged at respective locations in the circuit; and a hydraulic fluid reservoir (1011); a pressure fluid controlled steering actuator (1001) mechanically coupled to the steering arrangements; and comprising first and second actuator compartments (1002, 1003) hydraulically interconnected via respective first and second pressure supply terminals; said wheels comprising a self centering mechanism active in the absence of pressure supply in the hydraulic pressure circuit; and a steering controller (1006) arranged to control said pressure control modules in correspondence with steering signals received from a main steering unit. According to an aspect said first and second pressure supply terminals are interconnected via at least the first pressure control module; the first pressure control module coupled in series with the second pressure control module; and a fail safe mechanism is provided arranged to release, in a fail condition, first and second pressure control modules.
